NASA astronauts set for spacewalk after delay due to risk posed by orbital debris

Two NASA astronauts ventured out on a spacewalk on Thursday to replace a faulty antenna on the International Space Station, facing what NASA called a minimally heightened risk posed by orbital debris left from a Russian missile test weeks ago.

The planned 6-and-1/2-hour spacewalk began at 7:10 a.m. Eastern time (1210 GMT) as astronauts Thomas Marshburn and Kayla Barron exited an airlock of the orbiting research lab some 250 miles (400 km) above Earth to begin their work.

“Sun’s coming up and you will be over South America in a couple of minutes,” mission control told the astronauts as they exited the airlock.

The start of the “extra-vehicular activity” (EVA) followed a 48-hour delay prompted by an orbital debris alert – believed to be the first such postponement in more than two decades of space station history – which NASA later deemed inconsequential.

The origin of the debris in question was left unclear by NASA, though a spokesperson said there was no indication it came from fragments of the defunct satellite that Russia blew to pieces with a missile test earlier this month.

Thursday’s outing is the fifth spacewalk for Marshburn, 61, a medical doctor and former flight surgeon with two previous trips to orbit, and a first for Barron, 34, a US Navy submarine officer and nuclear engineer on her debut spaceflight for NASA.

Their objective is to remove a defective S-band radio communications antenna assembly, now more than 20 years old, and replace it with a spare stowed outside the space station.

The space station is equipped with other antennae that can perform the same functions, but installing a replacement system ensures an ideal level of communications redundancy, NASA said.

Marshburn will work with Barron while positioned at the end of a robotic arm maneuvered from inside by German astronaut Matthias Maurer of the European Space Agency, with help from NASA crewmate Raja Chari.

The four arrived at the space station Nov. 11 in a SpaceX Crew Dragon capsule launched from the Kennedy Space Center in Florida, joining two Russian cosmonauts and a NASA astronaut, Mark Vande Hei, already aboard the orbiting outpost.

Four days later, an anti-satellite missile test conducted without warning by Russia generated a debris field in low-Earth orbit, forcing the seven ISS crew members to take shelter in their docked spaceships to allow for a quick getaway until the immediate danger passed, NASA said.

The residual cloud of debris from the blasted satellite has dispersed since then, according to Dana Weigel, NASA deputy manager of the ISS program.

NASA has calculated that remaining fragments continue to pose a “slightly elevated” background risk to the space station as a whole, and a 7% higher risk of puncturing spacewalkers’ suits, as compared to before Russia’s missile test, Weigel told reporters on Monday.

NASA determined those risk levels fall within an acceptable range and moved ahead with preparations for a spacewalk on Tuesday as originally planned, only for mission control to delay the EVA mission hours before it was to start.

The operation was postponed after NASA received notice from US military space trackers warning of a newly detected debris-collision threat. NASA concluded later there was no risk to spacewalkers or the station after all, and the antenna replacement was rescheduled for Thursday morning.

Thursday’s exercise marks the 245th spacewalk in support of assembly and upkeep of the space station, and the first on record delayed due to a debris alert, NASA spokesperson Gary Jordan said.

Asian art fair in Hong Kong aims to bounce back after COVID-19 years


The organizers of Art Basel Hong Kong, one of Asia’s leading contemporary art fairs, said on Tuesday they are bullish on art market prospects in the region, with China and Hong Kong now having lifted all COVID-19 lockdown restrictions.
The annual fair, which also has iterations in Basel, Paris, and Miami Beach, runs from March 23-25 in Hong Kong.

The number of galleries has increased to 177 this year from 130 in 2022, with 32 countries and territories across Asia, Europe, the Americas, and Africa participating.
“Despite the challenges of the pandemic, the Asian art market has also remained resilient, with Greater China accounting for 20 percent of worldwide sales by value and ranking second as the second largest regional art market in the latest edition of the Art Basel,” Art Basel CEO Noah Horowitz told reporters.
Hong Kong attracted 56 million visitors in pre-pandemic 2019 but shops now sit vacant and Chinese visitors, who once propelled the city’s art market, have yet to return in droves.
Leading international galleries at Art Basel this year include Gagosian, Hauser & Wirth, Lehmann Maupin, Victoria Miro, Pace, Perrotin, White Cube and David Zwirner.
In a mall near the glitzy halls of Hong Kong’s harborfront convention center where Art Basel, the show has installed a 10-meter-tall inflatable sculpture of Egyptian pharaoh Tutankhamun titled ‘Gravity’ by Los Angeles-based artist Awol Erizku.
Hong Kong’s government has welcomed the art fair as it strives to reinvigorate Hong Kong’s economy after a nearly three-year slump from factors including tough COVID-19 lockdowns, a closed border with China, and a security crackdown.
Hundreds of thousands of people have left the territory since June 2020, when a sweeping national security law was passed that has been used to curb freedoms and arrest scores of opposition democrats and shutter liberal media outlets.
Some Western governments have criticized the law as a tool of repression, but China asserts it brought stability after pro-democracy protests in 2019.
Art Basel said it had respected creative expression.
“We don’t have any censorship process in the show. We haven’t really changed the process of the show since 2013,” said Angelle Siyang-Le, the director Art Basel Hong Kong.

Actress Gwyneth Paltrow to stand trial for ski crash in upscale Utah resort


Gwyneth Paltrow is scheduled to stand trial on Tuesday in a lawsuit filed by a retired optometrist who said that the actress-turned-lifestyle influencer violently crashed into him in 2016 while skiing in Utah at one of the most upscale ski resorts in the United States.

Terry Sanderson, 76, said Paltrow was cruising down the slopes so recklessly that they collided, leaving him on the ground as she and her entourage continued their descent down Deer Valley Resort, a skiers-only mountain known for its groomed runs, après-ski champagne yurts and posh clientele.

For the latest headlines, follow our Google News channel online or via the app.
“Gwyneth Paltrow skied out of control,” Sanderson’s attorneys claim in the lawsuit, “knocking him down hard, knocking him out, and causing a brain injury, four broken ribs and other serious injuries. Paltrow got up, turned, and skied away, leaving Sanderson stunned, lying in the snow, seriously injured.”

In a case that has lasted years since the 2016 incident, Sanderson is suing Paltrow for $300,000 — claiming that the accident in Park City was a result of negligence, and left him with physical injuries and emotional distress.

At ski resorts, the skier who is downhill has the right of way, so a central question in the case is who was further down the beginner’s run when the collision transpired. Both Paltrow and Sanderson claim in court filings that they were further downhill when the other rammed into them.

Sanderson also accused Deer Valley and its employees of engaging in a “cover up” by not providing complete information on incident reports and not following resort safety policies.

After his initial lawsuit seeking $3.1 million was dropped, Sanderson amended the complaint and he is now seeking $300,000. Paltrow — the Oscar-winning actress known for her roles in “Shakespeare in Love” and Marvel’s “Iron Man” movies — filed a counterclaim in response, seeking attorney fees and $1 in damages.

Paltrow has countered that he was actually the culprit in the collision, is overstating his injuries, and trying to exploit her celebrity and wealth. In addition to her acting career, she is also the founder and CEO of the high-end wellness company, goop.
In court filings, her attorneys deny Sanderson’s claims and allege that he was the one who crashed into her — a collision in which she sustained a “full body blow.” Her counterclaim alleges that members of Paltrow’s group checked on Sanderson, who assured them he was fine. It casts doubt on his motive and claims of injury, noting that before the incident, he had 15 documented medical conditions.

“He demanded Ms. Paltrow pay him millions. If she did not pay, she would face negative publicity resulting from his allegations,” her attorneys wrote in a 2019 court filing.

The trial in Park City is slated to last longer than a week.

Rafa Nadal out of top 10 for first time since 2005


Rafa Nadal’s absence from Indian Wells saw the 22-times Grand Slam champion slip out of the top 10 for the first time since 2005 on Monday but the Spaniard will still be the “man to beat” at the French Open if he can get back to full fitness.
Nadal was forced to skip the Masters 1000 event in California, where he reached the final last year, as he continues his recovery from a hip issue that ended his Australian Open title defense in the second round in January.

For the latest headlines, follow our Google News channel online or via the app.
Unable to defend the 600 points from Indian Wells resulted in Nadal dropping four places to 13th in the rankings, ending his record 912-week stay inside the top 10, which began when current number one Carlos Alcaraz was not even two years old.
However, with Nadal preparing to return to action at the Monte Carlo Masters next month ahead of the French Open, which he has won 14 times in his career, his time outside the top 10 might be short.
World number four Casper Ruud, who lost to Nadal in the Roland Garros final last year, said he would not be shocked to see the 36-year-old lift the trophy once again.
“It wouldn’t surprise me because he’ll probably use these weeks and these months, as he’s preparing for exactly Roland Garros,” Ruud told Eurosport as part of the ‘Ruud Talk’ series.
“It doesn’t matter if he loses in Monte Carlo or Rome or Madrid. The only thing that’s probably on his mind these days is just to be fit, be healthy, and be ready for Roland Garros.”
Tennis lost two of its greats when Serena Williams and Roger Federer bowed out of the sport last year, but Nadal and rival Novak Djokovic are still soldiering on.
Djokovic, who turns 36 in May, has shown few signs of slowing down and drew level with Nadal on 22 Grand Slams by winning the Australian Open.
“For the whole tennis world it would be nice to see one last showdown at Roland Garros,” former US Open champion Dominic Thiem said, adding that Djokovic would be favorite to win the remaining Grand Slams this year.
“The only tournament is Roland Garros: if Rafa is fit there, it’s exactly the opposite. He’s the man to beat when he won the tournament 14 times, it’s crazy.”
